Overview

Equinox SuperSerial Technology (SST) RJ Boards are intelligent, high-speed (up to 921.6 kbps) multiport boards providing high performance serial I/O solutions for ISA bus systems. All port interfaces are standard RS-232 with partial modem control (one control signal out and two control signals in) and voltage surge protection. (If your application requires EISA, PCI, Micro Channel bus and/or full modem control, contact your Equinox reseller for information on other SST products.)

SST Boards appear to the system host processor as memory. That is, they are memory mapped devices. Each board is automatically mapped into system memory at the time of device driver installation.

The device driver soft-configures all boards each time the system is initialized (booted). See PN 560093 (Windows NT, Windows 95,

Novell AIO, and OS/2), PN 560084 (UNIX SVR3.2, SCO, and

XENIX) or PN 560085 (UNIX SVR4 STREAMS) for detailed device driver information.

The SST board (shown in Figure 1 below) occupies a single ISA slot in the host computer and provides the intelligent functions to "offload" the CPU serial communications processing tasks.

Figure 1. SST-4I/RJ Multiport I/O Board

Use the following procedure to install your SST-4I/RJ Board.

Alternatively, you may follow the installation instructions presented in your host system documentation.

1. Set the host computer system power switch to OFF and disconnect the power cord.

2. Locate a free expansion slot.

3. Insert and secure the board firmly into the expansion slot.

4. Replace the power cord and turn the host computer system ON.

Plug and Play

ISA SuperSerial Technology Boards must be assigned a unique I/O base address. This can be accomplished by the use of ISA Plug and

Play (PnP) or the I/O Base Address Switch S1.

PnP for ISA boards is not currently supported by all Operating

Systems (OS). Consult your OS documentation to determine if it supports PnP.

If PnP is not supported by your OS, or if you are unsure, place the

PnP jumper (JP1) in the position closest to switch S1. This will disable PnP and enable the 4 position I/O Base Address switch as shown below.

If multiple ISA boards are installed in the same system, a different address must be assigned to each board. (This is automatically accomplished if PnP is utilized.) This procedure should be performed before the board is physically installed.

Device Cabling

Figure 2 below shows the RJ-11 port orientation and pin-outs for the

SST-4I/RJ. Note that pin 3 acts as Data Terminal ready (DTR) when connected to a modem (i.e. it will be dropped when the operating system wants to disconnect the call). It will act as Request To Send

(RTS) when a device is directly connected and hardware flow control is enabled.

Figure 2. SST-4I/RJ Port pin-outs

Below and following on the next page (see figures 3, 4 and 5) are three cable diagrams detailing how to build your own cables to go between a SST-4I/RJ and your terminals, printers, PCs, modems, etc.

Diagnostics

Use Equinox RJ Loopback connector 750082 with the ssdiag or eqnloop diagnostic utility (see software manual PN 560084, PN

560085, or PN 560093) and set parameters to external loopback.

Modular Adaptors

Modular adaptors are available to convert modular jacks to DB-25 or

DB-9 connectors. Table 2 below describes the modular adaptors available from Equinox. Use a standard reversing 4-wire (data only) or 6-wire RJ-11 modular cable with these adaptors.

Table 2. Modular Adaptors

The adapters listed in table 2 above, with modular cables as shown below in table 3 may be used to attach devices to the SST-4I/RJ. The outer two wires which support control signals are omitted when using

4-wire cables. Standard modular cables used for telephones are always reversing (e.g., pin 1 is connected to pin 4, etc.) and are typically 4-wire. If a user supplied modular cable is used, make sure

the cable is reversing (as shown in figure 6 below).
